A novel design of force to rebalance control for a hemispherical resonator gyro (HRG) based on FPGA is demonstrated in this paper. The proposed design takes advantage of the automatic gain control loop and phase lock loop configuration in the drive mode while making full use of the quadrature control loop and rebalance control loop in controlling the oscillating dynamics in the sense mode. Firs...

WtNTER 2006 I nstitutional money managers develop risk models and optimal portfolios to match a desired risk/reward profile. Utility functions express risk preferences and implicitly reflect the views of fund trustees or directors. Once a manager determines a target portfolio, maintaining this balance of assets is non-trivial. A manager must rebalance actively because different asset classes ca...

Abstract For particle collider searches for physics beyond the Standard Model in final states with jets and missing transverse momentum, events from QCD multi-jet processes are an important challenging background contribution. The CMS ATLAS experiments have previously developed data-driven methods designed to succeed where Monte Carlo suffer large theoretical experimental uncertainties. One suc...

We empirically examine whether firms engage in a dynamic rebalancing of their capital structures while allowing for costly adjustment. We begin by showing that the presence of adjustment costs has significant implications for corporate financial policy and the interpretation of previous empirical results. After confirming that financing behavior is consistent with the presence of adjustment cos...

We empirically examine the trade-off theory of capital structure, allowing for infrequent adjustment. After showing that the behavior of financing decisions (security issuances and retirements) is consistent with direct evidence on external financing costs, we use a dynamic duration model to show that firms behave as though adhering to a dynamic trade-off policy in which they actively rebalance...
